To (ZZZ whom may concern:

lie it known that we, \VILLIAM T. BAR- noon and Tl ILLL-JI L. MnnsrnLnnn, citizens of the United States, and residing at Detroi county of Jayne, and State of Michigan have invented a new and Improved Stove-Door of which the following is a specification.

This invention relates to the fire and ash doors of stoves and furnaces and its object is to provide a door casing and a pair of doors mounted thereon, of which the upper may swing on horizontal. pivots at its lower end and the lower on vertical pivots at one side. A further object of this invention is to mount the upper or fire door so it may serve as a coal chute and to so construct the two doors that they constitute a substantially fiat continuous surface.

This invention consists in a fire door mounted on horizontal pivots which extend into sockets formed in-the lower ends of its sides and an ash door mounted below the fire door on vertical pivots just below the fire door the fire door having a ledge at its lower edge set back from its race against which the ash door fits so that its face is flush with the face of the fire door. It further consists in rounding the lower ends of the sides of the fire door and providing a pair of ears on the door casing against which the rounded ends of the sides may bear to form a tight joint. It also consists in providing a stop on the casing against which the l dge at the lower edge of fire door may bear when the door is swung out on its pivots, to hold the door in an inclined position so as to constitute a chute for the fuel. It also consists in the details of construction illustrated in the accompanying drawing and particularly pointed out in the claims.

In the drawings, Figure 1 is a front elevation of the doors and the door casing. Fig. 2 is a section on the line 2- of Fig. 1. Fig. 3 is a similar view with the upper door swung down. Figs. at and 5 are perspectives showing engaging parts of the two doors and the casing.

Similar reference characters refer to like parts throughout the several views.

The door casing 1 may be integral with or separate from the body of the stove or furnace to which it pertains. It is provided with the small brackets 2 having pintles 3 on which the upper door 4 is mounted and with the lugs 5 carrying the pins (3 of the lower door 7 which has lugs 8 to receive these pins.

The doors have fiat faces which are sul stantially continuous with each other and inclined sides which are marked 9 and 10 in the upper door and 12 and 13 in the lower door. Bosses 1% are formed on the sides 9 and 10 near their lower ends and these bosses have recesses 15 and holes 16 to receive the pintles 3 on the brackets. The lower ends of the sides 9 and 10 are rounded and normally engage and rub on the curved upper edges of the small lugs 17 on the casing so that there will always be a tight joint at the lower eno of the upper door except when that door is open.

An ofi'set ledge 18 is formed at the lower end of the face of the upper door, and against it the upper edge of the lower door normally bears as indicated in Fig. 9. The upper ends of the sides 12 and 13 of the lower door also fit against these lugs 17, as shown in Fig. 5, the upper corners 19 of the sides of the lower door fitting against the tops of these lugs and against the lower ends or the sides 9 and 10. These lugs are substantially hidden by the brackets 2.

The casing 1 is preferably formed with a transverse member 20 provided with a lip 21 against which the ledge 18 bears when the door is swung open as shown in Fig. A transverse apron 22 may be supported in any desired manner with its upper edge preferably near and on about the same in clineas the lining 23 of the door.

\Vhen the two doors are closed, a tight joint exists all around their edges and between them. The upper edge of the front of the lower door being above the ledge 18 there is nothing to prevent this lower door being swung open at any time without disturbing the upper door. The ledge 18 of the upper door travels inwardly when that door is opened so that the lower door is not -dis turbed thereby. iVhen the upper door is open, any fuel that may fall from the shovel will be caught by the lining 93 and will be thrown into the stove when the upper door is closed or the door may be used as a chute to guide the fuel into the stove, the angularity of the door when swung open being a matter 0'? choice and depending merely upon the position of the lip 21.

The sizes and proportions of the various parts may all be changed by those skilled in this art without departing from the spirit of our inventioiras set forth in the following claims.

We claim 1. In a door construction, the combination of a casing having a pair of lugs and a door hinged thereon to swing on a vertical axis, a pair of brackets attached to the casing and positioned just above said door and having pintles in horizontal alinement parallel to the casing, a second door mounted on said pintles and having its face substantially uniform with the face of the lower door, said casing having a cross bar adapted to be engaged by the lower edge of the face of said upper door when swung down to open position. 7

2. In a door construction, the combination of acasing, a door hinged thereto to swing on a vertical axis, a pair of brackets and horizontal pintles mounted on and parallel to the casing on each side of and just above said door, a second door mounted on the pintles and having its lower end rounded with the axis of the door as a center, a lug mounted adjacent each bracket and having an upper edge curved to fit the lower end of the door, said upper door having a ledge at its lower end against which the upper edge of the lower door may bear, a lining for the upper door, and a transverse apron so positioned as to constitute with the lining of the door a substantially continuous surface to receive the fuel.

3. In a door construction, the combination of a casing, horizontal pivots mountedonthe casing and an upper door mounted thereon at its lower edge to swing outwardly, vertical pivots also mounted on the casing and a lower door Inounted thereon, the faces of said doors constituting a substantially continuous plane spaced apart from the casing, and substantially continuous sides extending from the outer edges of the doors to the casing, the adjacent edges of the doors engaging and one of them being provided with an overlapping ledge extending across the joint between them.

4. In a door construction, the combination of a casing and a pair of horizontal pivots mounted thereon and parallel thereto, an upper door mounted to swing on said pivots, a pair of vertical pivots mounted on the casing and parallel thereto, a lower door mounted to swing on said vertical pivots, the faces of both of said doors being spaced apart from said casing and constituting a substantially continuous plane, said upper door having sides extending from its face to the casing along its side and top edges, and said lower door having sides extending from its face to the casing along its side and bottom edges. 7

5. In a door construction, the combination of a casing, an upper door mounted on the casing to swing on a horizontal axis parallel to the casing near the lower edge of the door, and a lower door also mounted on the casing in engagement with the upper door to swing on a vertical axis, the faces of the doors when closed being in substantially the same plane, and means on the casing adapted to be engaged by the upper door to limit its outer movement.
